Glass Nozzle Polishing Technique

Nozzles for use in projecting ink droplets for ink jet printing must have precise
exit characteristics. These characteristics include flatness of the nozzles and
nozzle array exactly perpendicular to the axis, an optical polish, and edges of
nozzles chip free and slightly rounded.

After a normal lapping procedure to obtain flatness, eliminate the normal
rough polish step, and do only a final polish with a soft and extremely fine cloth
pad with Iu Cerium oxide. This pad is able to maintain the flatness of glass
nozzles with an excellent surface finish.
